SASH HOLDER AND TIGHTENER.

SPECIFICATION forming part of Letters Patent No. 252,472, dated January 1'7, 1882.

Application filed November 11, 1881. (No model.)

buses, is a great and objectionable annoyance,

and it is also well known that the glass is fre-.

quently broken in car-windows in consequence oftheignorance or awkwardness of persons who endeavor to raise the sash but release the hold before the bottom of the sashhas been swung aside so as to descend into its seat; andmy invention is designed to obviate this accident bycausing the sash to swing aside automatically when it has been raised to the proper height; and to this end it consists in an elastic device which is preferably attached to the sash, and projects therefrom on opposite sides and. at diflerent points of elevatiom'which, when the said sash is raised to its full height, will engage with the casing, and by its elastic pressure cause the sash to swing aside into the desired position. An elastic device capable of this service may be made in a variety of ways, and a simple spring may accomplish it; but I prefer, for other reasons, to employ a pair of elastic rollers set upon pivots at different elevations, one on each side of the center of thickness of the sash, so that one shall project from one side and the other from the other side. By this means the sash will have an elastic bearing upon the casing in front and backof the sash, and at different elevations, so that while said elastic hearings will quiet the rattling of the sash they will also tend to deflect the sash fromthe perpendicular, so that it will drop into its seat without special care on the part of the person moving it.

That others may fully understand my improvement, I will particularly describe it, having reference to the accompanying drawings, wherein- Figurel is a perspective view, showing my invention in operative position. Fig. 2 is a vertical section of the same. Figs. 3, 4, 5 represent the device in detail.

A is the sash, and Bis the casing provided with the-cell or case G, into which the sash may descend when the window is to be opened. At the top of the cell 0 thesashway is widened, so as to form a seat, b, to hold the lower edge of the sash when the window is closed. This structure is in common use, and will be understood. I

It is well known that when the sash is raised its bottom edge must be pushed outward, so

that itmay descend into the seat I). The top part of the sashway in the casing B is wide enough to accommodate the thickness of the sash, while the bottom of said sashway is in width more than twice the thickness of the sash, so that when the sash is pushed up its upper edge is confined in the sashway.

By my invention the sash is provided with an elastic device which engages with the casing at the inner side of the sash and causes the bottom to swing outward, 'so' that it can descend into the seat b.

I prefer to employ on the inner side of the sash an elastic roller, E, of india-rubber, for this purpose, and the effect is improved by placing a similar roller, F, on the outside a little higher than the roller E. (l ne of said rollers will therefore push the bottom of the sash outward, and the other will push the top inward, and they will therefore co-operate to produce the desired result.

- Springs of other forms may be employed, if 8 desired, such asflat metallic springs, &c.

The elastic rollers E-F are mounted in a small frame or fixture, as shown, so that they may be readily attached to the sash. This elastic attach mont not only serves to direct the sash into its sea-t properly, but it also prevents the sash from rattling.

Having described my invention, I claim as new- 1. A sash-frame broad at the bottom and provided with a cell, 0, and seat b, and a sash, A, adapted to move therein, combined with an elastic device attached to said sash at or near its top, projecting from said sash on opposite sides atdifierent points of elevation, and adapted. to press the bottom of the sash outward toso as to project from opposite sides at differ- ;vard its seat i), buithoulg otft contgct witth tthe ent elevations, asand for the purpose set forth.
